    Computer Aided Layout Planning for Manufacturing Industries of Ethiopia (Case in Kotebe Metal Tools Factory)
    (Addis Ababa University, 2009-12) Ameha, Mulugeta; Daniel, Kitaw (PhD); Birhanu, Beshah (Mr.)
    Layout planning has been considered as one of the vital areas for improving performance of any business process. Its main concern is reducing cost by maximizing adjacency of high interaction components of a system or reducing material handling cost or distance between the components. Taking KMTF’s layout as a case, this study considered three approaches of layout design. The first approach utilized the improvement of the existing layout. Section wise exchange and machine wise exchanges are made to the current layout to arrive at a better layout than the currently being used layout. Making the exchange section wise and then using the machine arrangement obtained by this method to be further improved by machine wise exchange is observed to give better layout than improving the current machine arrangements. The exchange has been made according to CRAFT improvement routine. The second approach has been done to construct a new layout for KTMF sections using CORELAP construction routine and then improving the constructed layout using CRAFT improvement routine. But the current layout is observed to be better starting point for improvement using improvement routine than the constructed layout. This shows the current layout is good but can further be improved by using improvement routines. To show the applicability of the approach another study published by Yugoslav Journal of Operations Research has been explained. This approach is suggested to be used in planning a new layout. The third approach introduced is the roll forging machine into the improved layout. The approach assumes the Roll forging machine is used by four products and the dies for the four products are brought together with the machine. Accordingly location of the new Roll forging machine has been obtained using single facility layout problem. Finally, it is concluded that the current layout is a good initial layout for improvement using CRAFT algorithm and a better layout is achieved by improving the current layout. Furthermore, construction routine followed by improvement routine is concluded to be good means of arriving at good layout in initial design of layouts. The improved layout and Roll forging are recommended for KMTF shop floor.

    Service Quality Measurement and Enhancement Approach for Banking Sector: - Case of Development Bank of Ethiopia
    (Addis Ababa University, 2022-01) Habte, Alemnew; Ameha, Mulugeta
    Service quality has stood on the very importance for the service industry. Service Quality has been identified as one of the most effective means of building a competitive position and improving organizational performance. With current status on the banks industry, competitions are becoming fierce which in turn clients are raising their expectations for high service quality. Beside to this, the usual core process of loan with the associated loan cycle time has a great influence on the service delivery. This research was conducted on service quality measurement and enhancement approach for bank sector and Development Bank of Ethiopia (DBE) selected as a case company. For this study purpose, the research was mainly targeted interviewing and questioning the top management of the DBE to find the root causes of customer complaints. From the interview and post analysis, eight (8) main root causes of customer complaints were found within the selected case company. In finding the key solution for the raised root causes, understanding of the explicit loan process of the DBE was conducted which depicts that project financing and lease financing loan modalities prevails the most. In such a way, this research purely revolves on these processes to investigate the service quality. This research used the integration of SERVQUAL-Kano with QFD for identifying the customer requirement and for the subject decision of the technical requirement of the Bank using the AHP approach. The researcher prepared a questionnaire in English and Amharic for SERVQUAL and KANO model, SERVQUAL model was used to measure the current service quality and identify the weak features but no prioritized features for service improvement. Therefore, Kano model was used for categorization and prioritization of the weak feature. From the results of SERVQUAL and KANO models, seven features were selected by DBE experts to service improvement into HOQ. Through the QFD method, adopt peer to peer has the best technical requirement and conducting relevant training has the second technical requirement to answer the customer needs. Therefore, Adopt peer to peer and conducting relevant training will improve in the case company 13.10% and 11.65% respectively. The researcher recommended the case company to start with establishing of quality planning, quality control, and quality goals as per customer requirements and follow the continuous improvement of service quality.
